A project costs €50 000 today and returns €8 000, €13 500, €10 000, €17 500, €12 000 at the end of years 1 to 5. Assume cash flows arrive evenly through each year. Find the payback period PB in years.
NPV & IRR worksheet with answers
A project costs €20 000 today and returns €6 500 at the end of each year for 5 years. The required rate of return is 6%. Find the net present value NPV.
A project costs €200 000 today. It generates €20 000 at the end of the first year, and the cash flow then grows by 3% per year forever. The cost of capital is 12%. Find the net present value NPV.
An investment of €30 000 gives these cash flows at the end of years 1 to 3: €12 000, €14 000, €11 000. The cost of capital is 10%. Find the net present value NPV.
A project costs €20 000 and returns €10 500, €7 500, €7 500, €11 500 at the end of years 1 to 4. Cash flows can be reinvested at the cost of capital of 6%. Find the modified internal rate of return MIRR in percent.
An investment of €80 000 returns €15 500 at the end of each year for 9 years. Find its internal rate of return IRR in percent.
